Residence time (means ± SE) and first choice (%) of Trissolcus mitsukurii females in Y-tube olfactometer exposed to odours from stink bug–plant systems. Treatments consisted of volatiles from soybean plants bearing an egg mass of Arma custos, Dolycoris baccarum, Halyomorpha halys, or Nezara viridula, or volatiles from cauliflower plants bearing an egg mass of Eurydema ventralis. Control consisted of a clean soybean or cauliflower plant. N number of responding insects. N.R. number of not-responding insects (discarded from the analysis). Planned comparisons were tested within GLM with Gaussian error distribution (residence time) or with binomial error distribution (first choice).
